Hello, i'm 16 and yesterday during my 2nd to last class my pubic area started to hurt, after i got home i went to look why it hurt so bad and i had a huge bump, about the size of mesquito bite but it doesn't seem to have a place where something punctured the skin, it hurts to touch around the bump or if anything just slighty touches it, after a day it doesn't seem to have healed or moved and the pain hasn't gone down, ic ant describe it more than just a bump about two inches above my penis and to the right a little bit

Oh and i'm sexually active i have sex, i've only had intercourse with one woman but i have given oral and recieved oral from another one any ideas, Oh and i have another problem, for a few years every time i piss it burns unless i drink excessive amounts of water, i do not have any discharge that i have seen and i have been tested mutliple times for Uti, or kidney stones etc and all came up negative
